About Richard Feynman

American theoretical physicist and Nobel laureate (1965).

“One has to have the imagination to think of something that has never been seen before, never been heard of before.”

“The highest forms of understanding we can achieve are laughter and human compassion.”

“Scientific knowledge is an enabling power to do either good or bad — but it does not carry instructions on how to use it.”

“A little flesh, a little breath, and a Reason to rule all—that is myself.”

“Knowing others is intelligence; knowing yourself is true wisdom.”

“One must learn to know oneself before knowing anything else.”

“Wouldst thou other men know, look thou within thine own heart.”

“I could give you no advice but this: to go into yourself and to explore the depths where your life wells forth.”

“The basic stimulus to the intelligence is doubt, a feeling that the meaning of an experience is not self-evident.”
